-1.0 Overview
-
- This is the README file for the sample loaded file system.
-
-
-2.0 Preparation
-
- To use this module, you must have a kernel the does *NOT*
- have an existing "kernfs" file system in it. To determine
- if your system has the "kernfs" file system in it, check
- the build file for your kernel (usually this file is named
- "/sys/i386/conf/GENERICISA") for the following:
-
- options KERNFS
-
- By default, NetBSD has this file system compiled as part
- of the kernel; if you wish to use this example with NetBSD
- you will have to remove this "options" line and rebuild
- your kernel.
-
- Note: The file "/usr/include/sys/mount.h" must have the
- "kernfs" file system type in it for this example; if you
- do not have the following line in this file, you will not
- be able to use this example:
-
- #define MOUNT_KERNFS 7
-
- This line is created by applying the "kernfs" patches to
- your system. NetBSD as distributed already has these
- patches applied; if you are running vanilla 386BSD, you
- will have to locate and add these patches to use this
- example.
-
-
-3.0 Directions
-
- To test the module, do the following:
-
- cd module
- make load
-
- A load message (the copyright) will be printed on the console.
-
- You must then add the following line to the "/etc/fstab" file:
-
- kernfs /kern kernfs rw 1 1
-
- At the root prompt, type the following:
-
- mkdir /kern
-
- Ignore the following error if it occurs:
-
- mkdir: /kern: File exists
-
- Again at the root prompt, type the following command:
-
- mount /kern
- cd /kern
- cat version
-
- This will verify that the module is working correctly.
-
-
-4.0 Recovering resources
-
- The file system consumes 8 pages of memory when loaded; it
- can be freed up by unloading it. To unload it, type the
- following from the directory this file is in:
-
- cd module
- make unload
-
- The file system will be unloaded by name.
-
-
